Android应用程序之间共享文字和图片(一)

以下为TestReceiveShare1工程

MainActivity如下:

package cn.testreceiveshare1;
import java.util.ArrayList;
import android.net.Uri;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.TextView;
import android.app.Activity;
import android.content.Intent;
/**
* Demo描述:
* 非系统自带Android应用之间传递文字和图片
* 即在两个自写的应用之间传递文字和图片
*
* 注意事项:
* 先部署TestReceiveShare1工程
* 再部署TestShare1工程
